As a thought exercise: If the sharp dividing line is submission to authority, would our Orthodox friends then be “protestant” by that definition because they don’t fully submit to the authority of the Roman Pontiff?
Forgive me as I muse a bit, ben, and I may ramble, but I promise I will bring it back and close the circle.
So I have been in many discussions with atheists and their “ace in the hole” seems to be this: the problem of evil.
No honest Believer can state that atheists do not have a valid reason for rejecting Theism.
Or, to put it without the double negatives: the problem of evil appears to be a valid reason for people to reject the Truth. It is a stumbling block to almost all thinking atheists.
Similarly, the schism between East and West appears to be the non-Catholic’s “ace in the hole”.
No honest Catholic can state that non-Catholics do not have a valid reason for rejecting Catholicism, based on this great divide that exists between these two Churches.
Or, to put it without the double negatives: the great schism appears to be a valid reason for people to reject Catholicism. It is a stumbling block to almost all thinking non-Catholics.
So you are right, ben. I really have no answer for you on this.
However, while I am not a conspiracy theorist, and do not see the devil lurking in every corner, this thought has occurred to me: if I were going to do everything I could to prevent the wavering atheist*–one who is possibly considering swimming into the River of Deism–what I would whisper is this: * but how could there be a God when there is .
*
That would be enough, don’t you think, to stop the wavering atheist right in his tracks?
*And what would be more of a loss for the devil than to have an atheist swim into the River?
Similarly, if I were the devil and were going to do everything I could to prevent the wavering Lutheran*–one who is possibly considering swimming the Tiber River–what I would whisper is this:
but how could the Catholic Church be the One True Church when there is a sharp divide between the East and the West?
*And what would be more of a loss for the devil than to have a Lutheran swim the Tiber?
(NB: this is a post written by a Catholic, of course, with a Catholic POV, so please do not read any condescension into this. You must understand that a Catholic would believe that the devil does not want a Lutheran to be a Catholic. I would not assign any condescension to you were you to offer a post in which you mused about the devil doing everything he could to prevent me from joining the Lutheran Church

).
So, to close the circle: if you can see how the problem of evil–while indeed a problem–ought not prevent an atheist from being a Believer…
then perhaps you can see how the problem of the schism–while indeed a problem–ought not prevent a non-Catholic from being a Catholic.
